Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74BCT541ANS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Logic type: Buffer, Non-Inverting
• Bit configuration: 1 element, 8 bits per element
• Output configuration: 3-State
• Output current ratings: 15mA (high), 64mA (low)
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C

Mechanical Specifications:

• Package type: 20-SOIC surface mount
• Physical dimensions: 0.209" width, 5.30mm width equivalent
• Mounting technology: Surface mount

Compliance Requirements:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The SN74BCT541ANSR qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format (Tape & Reel versus individual unit) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The SN74BCT541ANSR is the direct equivalent substitute for the SN74BCT541ANS. Both components are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters including logic function, bit configuration, output characteristics, supply voltage, operating temperature range, and package dimensions.

The SN74BCT541ANSR maintains Active product status, ensuring continued availability and long-term supply chain viability compared to the Last Time Buy status of the SN74BCT541ANS. Both components satisfy ROHS3 compliance requirements and carry identical moisture sensitivity ratings.

The primary distinction between these part numbers is the packaging format: the SN74BCT541ANS is supplied as individual units, while the SN74BCT541ANSR is supplied in Tape & Reel format. This packaging difference does not affect electrical or mechanical compatibility and is determined by procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74BCT541ANSR directly replace the SN74BCT541ANS in existing designs?

A: Yes. The SN74BCT541ANSR is electrically and mechanically equivalent to the SN74BCT541ANS. All electrical parameters, including logic type, bit configuration, output current ratings, supply voltage range, and operating temperature specifications are identical. The 20-SOIC package dimensions are identical, enabling direct PCB footprint compatibility.

Q: What is the difference between SN74BCT541ANS and SN74BCT541ANSR?

A: The primary difference is packaging format. The SN74BCT541ANS is supplied as individual units, while the SN74BCT541ANSR is supplied in Tape & Reel format. Additionally, the SN74BCT541ANSR carries Active product status, whereas the SN74BCT541ANS is Last Time Buy. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74BCT541ANS and SN74BCT541ANSR are ROHS3 compliant and carry identical Moisture Sensitivity Level ratings of 1 (Unlimited). Compliance certifications are equivalent.

Q: What does Last Time Buy status mean for the SN74BCT541ANS?

A: Last Time Buy status indicates that the SN74BCT541ANS is no longer in active production. Existing inventory may be available, but future production is not planned. The SN74BCT541ANSR, with Active status, represents the recommended long-term supply source for this logic function.

Q: Can I use these parts interchangeably in high-volume production?

A: Yes, with consideration for packaging format. For high-volume assembly operations, the Tape & Reel format (SN74BCT541ANSR) is typically preferred for automated pick-and-place equipment. Individual unit packaging (SN74BCT541ANS) may be suitable for lower-volume or manual assembly processes.

Q: Are the 3-state output characteristics identical between these parts?

A: Yes. Both parts feature identical 3-state output capability with output current ratings of 15mA (high) and 64mA (low), enabling equivalent bus-driving and signal isolation functionality.
